A K-12 school's score is based on the data in the following table:

Subject Weight Grade
English 25% B
Math 25% D
Graduation rates 30% D
Career readiness 20% C

If an 'A' is considered 4.0, a 'B' is 3.0, a 'C' is 2.0, a 'D' is 1.0, and an 'F' is 0. What overall score will the school receive?

it is probably going to be a 3.0 because the score depends on the grade each section gets. in this case, since math graduation percentage is the same, I think majority is winner so I would 3.0. WARNING- I HAVE NO CLUE IF THIS IS RIGHT OR BUT I EDUCATIVELY MADE UP THIS ANSWER BECAUSE THIS SEEMS LIKE ITS JUST A LOGIC QUESTION.

Answer:

The overall score that the school will receive is 1.70

Explanation:

The overall score that the school will receive is a weighted average; that is, every value is multiplied by its assigned weight and then added to get the final value.

In this case, we can see that the most important thing for this score, converting letter to number scale, is the Graduation rates (30% out of the total 100%, scoring 1.0), followed up by English (3.0) and Math (1.0) with 25% and last Career readiness (2.0), with 20%.

Now, we calculate the score (converting percentages to decimal numbers):


\mbox{Score}= \sum^(4) _(i=1)grade_(i)*weight_(i)= 3.0*0.25+1.0*0.25+1.0*0.3+2.0*0.2=1.70
